The equity–efficiency trade-off and the intensity of COVID-19 pandemic government responses: evidence from US states
利用2020年美国各州横截面数据，研究发现政府应对新冠疫情的强度与公平-效率关系呈倒U型，且该效应取决于各州人均GDP水平。
The relation between equity and efficiency remains at the heart of regional policy. This study captures the effect of the COVID-19 pandemic government responses on the above-mentioned relation. To do so, we employ cross-sectional data from US states for 2020 and a spatial econometric model specification in the context of Corona policy effects. We find an inverted-‘U’ relationship between inequality and efficiency. Additionally, the effect of the intensity of government responses to COVID-19 on the equity–efficiency relation depends on the state’s per capita gross domestic product (GDP) levels.
